LASER SOURCE IN GUIDED OPTICS

摘要

The invention relates to a laser source consisting of a laser cavity (1) that can emit an optical beam (5) and a guided optic element (3). Said guided optic element comprises the following in one substrate: an input guide area (G1) comprising a mirror which is concave in at least one guide plane of the input area in such a way as to create an extended laser cavity with the laser cavity; an output area (G3) comprising at least one microguide (9) which is associated with at least one optical output (S1) of the source; and a planar accommodation guide area (G2) between the input area and the microguide. The input guide area can receive the optical beam emitted by the cavity and transmit the beam to the accommodation guide area which subsequently guides said beam towards the microguide. The invention is suitable for use in all fields requiring a laser source with only a few modes and, in particular, in the field of optical telecommunications.
